i2c communication of PIC'S

[volkan]

Hi all,

We are dealing with a project and using 6 uc's in it.Maximum length of the distance between 2 uc's is 2 meter. We thought that the best way of communicating each uc (1master 5 slave) is i2c. Can it cause a problem such these distances using i2c or do you recommend another protocol?

And if anybody made a project like communicating 2 uc's(not with eeprom because i always see this kind of communication in samples) pls send it. I have some problems while i was trying to communicate 2 16f877( one of them master one of them slave of course) but it didnt work on proteus.

I will be happy if you send any C codes about this.

Best wishes...

ive heard that its not benficial to use I2C if there isnt a requirement for it. you can use the UART instead of I2C. so only use I2C when there is no other option like if you have a sensor that has an I2C interface. but if I2C isnt a requirement, a serial interface is easier to implement.

go to http://www.winpicprog.co.uk and check the tutorials on that site. you can get assembly codes from there. and also check out the PICList http://www.piclist.com

i have the same problem with proteus. it runs crazy when simulating multiple micros.
